The Mano Decompositions and the Space of Monodromy Data of the q-Painlevé V I Equation The talk is based upon a joint work with Y. OHYAMA and J. SAULOY. Classically the space of Monodromy data (or character variety) of PV I (the sixth Painlevé differential equation) is the space of linear

Gregory Sankaran: Moduli of deformation generalised Kummer varieties
Two of the four known types of compact hyperkahler manifolds arise from K3 surfaces and two from abelian surfaces. The moduli spaces of polarised varieties of the K3 types have been extensively studied, but less attention has been paid to the abelian types. I shall describe some work in pr

Toy Ind3 - Part 04 - Log Kummer Correspondences
We introduce the definition of the Log-Kummer Correspondence. While there is not direct definition we can point to this is used throughout IUT3 and is what gives rise to Ind3. This is actually quite tricky. For example, a Log-Kummer correspondence doesn't exist for tensor packets but is i

Etale Theta - part 3 - Interior/Cuspidal Cyclotome and the cover Xu
Here is what we do: *explain the cyclotome appearing in the two step nilpotent quotient of Delta. This cyclotome is used for coefficients for the Kummer class of the Jacobi Theta function. *We construct covers Xu of a punctured elliptic curve which depends on a choice of l-torsion subgrou
